PyBamView

PyBamView visualizes BAM sequence alignments to accurately display insertions and enable multi-sample comparison for next-generation sequencing analyses.

Key Features:

• Accurate insertion visualization: Displays insertions within sequence alignments with explicit representation to improve detection of insertion events.
• Multi-sample alignment comparison: Supports simultaneous viewing and comparison of alignments across multiple samples for comparative analyses.
• BAM file support: Operates on standard BAM file formats to ensure compatibility with common NGS alignment outputs.
• Scalable handling of large NGS datasets: Processes large and complex next-generation sequencing alignment datasets to address representation challenges.
• Python-based processing: Implements core functionality using a Python architecture for integration into bioinformatics workflows.

Scientific Applications:

• Insertion and structural variation analysis: Facilitates examination and interpretation of insertions and other structural variants within alignments.
• Variant calling validation: Provides visual evidence to support validation and curation of variants detected by variant-calling pipelines.
• Comparative genomics: Enables cross-sample comparison of alignment features for studies in comparative genomics and population analyses.
• Investigation of complex genetic rearrangements: Assists in exploring complex rearrangements and alignment artifacts in NGS datasets.

Methodology:

Implemented in Python and processes standard BAM file formats.
